# README

This Dataverse entry contains radar data products and ancillary datasets used for figure generation in the paper "Entrained debris records regrowth of the Greenland Ice Sheet after the last interglacial". These files are referenced in plot scripts provided at https://github.com/nholschuh/DebrisTrains.

There are three main file types in this repository, easily filtered for by tag in the dataverse, described below.

## Music*.mat  (3D radar volumes)

These files contain 3D radar volumes produced using MUSIC direction-of-arrival processing. They can be used to interpret bed echoes and directional scattering/clutter structure.

Contents include:
- a 3D radar volume (along-track × depth/range × angle or direction-of-arrival space)
- coordinate axes (posotion, range, and angle bins)
- processing metadata

## SLC*.mat  (single look complex radar profiles)

These files contain standard single look complex (SLC) radar profiles. This is the conventional complex-valued radargram product (magnitude and phas), used for along-track slope determination

Contents include:
- complex radar data
- range axis (fast-time)
- along-track coordinate information and geolocation data
- processing metadata

## Angle*.mp4  (direction-of-arrival + bed power animations)

These are short animations that show how the along-track and across-track direction-of-arrival structure varies through the radar dataset, along with bed reflection power. 

## Software / provenance

The MUSIC and SLC products were generated using the Open Polar Radar (OPR) Toolbox. For details on the MUSIC and standard products, see:
